Patented Feb. 3, 1931 LOUIS ISGUR, OF ROXBURY, BOSTON, MASSACHUSETTS PATENT ol-Flcaj SKYLIG-HT Application led September 7, 1929. Serial No. 391,042.

This invention relates to skylights, and is more particularly concerned kwith a novel gutter construction for handling the water of condensation which terms on the under,

or inner side of the skylights.

The invention will be best understood by reference to the followingv description, when taken in connection with the accompanying drawings of one specific embodiment thereof,

1c while its scope will be more particularly pointed out in the appended claims.

In the drawings:

Fig. 1 is a plan of a portion of a skylight embodying the invention;

Fig. 2 is a sectional view, at an enlarged scale, on line 2 2 of Fig. 1;

Fig. 3 is a sectional view, atan enlarged scale, on line 3--3 of Fig. 1; and j Fig. 4 is a perspective view of a portion 2G of the rabbet strip with which the cross gutter is associated. Y Referring to the drawings, and to the embodiment of the invention which is illusv trated therein, there is shown a glazed structure comprising a plurality of glass members 5, Supported by an underlying support, herein a T-bar 6, having a vert-ical web 7 and two horizontal flanges 8. The T-bar constitutes a rafter, which is inclined, as are also the glass members which it supports.

Superimposed upon the T-bar is a gutter member 9, usually made of non-ferrous sheet metal, bent downwardly and inwardly about the flanges 8 to embrace the T-bar, and thence 85- downwardly and finally 'upwardly to provide main gutters or troughs 10. This gutter member is assembled with the T-bar by sliding one lengthwise onto the other. rSuperimposed on the gutter member is a clip 0r saddle 11, which is first laid upon the gutter member at the proper point, and then has its ends bent downwardly and inwardly beneath the fianges 8 in the same form as the n gutter member. This clip or saddle provides an anchor for the head of a stud or bolt 12, which extends upwardly through a space 13 between adjacent edges of two glass members 5, and through a cap 14, herein a chan- Y nel-like bar of nonferrous sheet metal hav- DU ing downwardly-directed edges 15, which rest upon a strip of cushioning material 16V superimposed upon and spanningthe adjacent edges of the glass members. A similar, but much thicker strip of cushioning material 17 is interposed between the, glass mem- 55 bers and the gutter member. These strips of cushioning materialare of course perforated at intervals to receive the studs or clamping screws. A nut 18 and a washer 19, applied to each screw, urges the cap to e0l ward the underlying parts, and this clamps them to the T-bar comprising the-strips of cushioning material and making a tight joint. It should also be understood that the skylight comprises a plurality of the described rafters, and that' two adjacent rafters support opposite edges of a plurality of the glass members 5.

Referring now to Figf, the adjacent horizontal edges of two glass members are spaced to receive between them a rabbet strip 20, which is bent to provide upper and lower flanges 21 and 22, the latter having a return bent portion 28, which is provided with a downwardly-directed lip 24, to cause any moisture which collects to drip therefrom into a cross-gutter 25. This cross-gutter rests at both ends on two of .the main gutters 10. in Fig. 2, one of its ends is thus shown resting upon ono of the main gutters. The crossgutter is supported principally in this manner, but is prevented from sliding downwardly along the main gutter by appropriate means, herein a downwardly-directed tab 26, best shown in Fig. 1i, herein conveniently 85 formed by slitting the return bent portion 23 of the rabbet strip along the line 27, 'and then bending the tab downwardly to form a flange at right angles to the rabbet strip. This tab is engaged by an upwardly-directed ange 28 on the cross-gutter, and thus prevents the latter from sliding downwardly along the main gutter, without the necessity of providing any fastening means whatever' for the cross-gutter. In other words, the cross-gutter is loosely mounted on the main gutter, but is prevented from sliding in a downward direction thereon.

Any moisture which collects on the under side of the upper glass member 5 and runs l down to the depending lip 24 of the rabbet strip drips therefrom into the cross gutter, and is conducted to the main gutters at opposite Aends of the cross gutter. rlhe water then descends in the main gutters in the usual way to appropriate outlets.

Having thus described one embodiment of the invention, but without limiting myself thereto, what l claim and desire by Letters Patent to secure is:

1. In a skylight structure, the combination of glass members having adjacent edges, va rabbet strip associated with said edges and having below said members a downwardly directed lip, a gutter below and spaced from said strip and extending lengthwise of said lip to receive water dripping therefrom, and means extending downwardly from said strip to said gutter to aiford support for the latter.

2. In a skylight structure, the combination of an inclined glass member, a horizontal strip beneath said member and presenting a downwardly directed lip, a gutter below and spaced from said strip and extending lengthwise of said lip to receive water dripping therefrom, and means connecting said strip to said gutter to afford support for the latter.

3. In a skylight structure, the combination of an inclined glass member, an inclined main gutter below said glass member, a horizontal strip beneath said member, a horizontal crossgutter extending lengthwise of, beneath and spaced from said strip to receive moisture therefrom and discharging into said maingutter and resting upon the latter, and means connecting said strip to said cross-gutter to prevent said cross-gutter from sliding downward along said main gutter.

4. ln a skylight structure, the combination of an inclined glass member, an inclined main gutter, below said member, a horizontal strip beneath said member and having a depende ing lip, a horizontal cross-gutter extending lengthwise of, beneath and spaced from said lip to receive moisture therefrom and discharging into said inain-gutter and resting upon the latter, and means connecting said strip to said cross-gutter to prevent said crosse gutter from sliding downward along said main-gutter.

5. ln a skylight structure, the combination of an inclined glass member, an inclined main gutter below said member, a .horizontal strip beneath said member and having a depending lip, a horizontal cross-gutter extending lengthwise of, beneath and spaced from said lip to receive m isture therefrom and discharging into said main-gutter and resting upon the latter, and a projection downwardly directed from said strip and engaging said cross-gutter to prevent the latter from sliding downward along said main-gutter.

6. In a skylight structure, the combination of glass members having adjacent edges, a rabbet strip associated with said edges, a gutter below and parallel with and spaced from said strip, and means extending from said strip downwardly to said gutter to afford support for the latter.

7. In a skylight structure, the combination of glass members having adjacent edges, a rabbet strip associated with said edges, and a gutter below and parallel with and spaced from said strip, said strip being provided with a downwardly directed projection which engagessaid gutter and affords support for the latter.

8. ln a skylight structure, the combination of glass members having adjacent edges, a rabbet strip associated with said edges, and a gutter below and parallel with and spaced from said strip, said strip being slit and bent downwardly to provide a projection which engages said gutter and affords support for the latter.

in testimony whereof, l have signed my name to this specification.
